论文摘要
带宽应用程序和服务的扩散强迫数据中心（DC）管理员优化可用资源的利用。确切地说，由于DC网络变得越来越复杂，并且需要大量数据才能有效调试和故障排除，因此管理流量的网络共享已大大增长。因此，我们使用带有波长的自由空间通信（FSO）与波长多路复用（WDM）技术来构建负责管理流量的灵活但高性能的逻辑网络。 FSO-WDM可以在视线（LOS）链接上提供可重构的多重拓扑。由于空间和处理能力原因，我们无法提供从每个数据架到网络管理架的直接连接。另外，将数据架分组在一起，因为每组在时间长时间内进行服务与其平均到达率相匹配。由于数据机架显示出不同的到达率，因此热点架以更长的服务时间分配。评估结果表明，F4Tele在昂贵的解决方案（基准）附近进行了高吞吐量。
The proliferation of bandwidth-hungry applications and services forces datacenter (DC) administrators to optimize the utilization of available resources. Precisely, the network share of management traffic has grown significantly because DC networks are becoming more sophisticated and require a massive amount of data for efficient debugging and troubleshooting. Accordingly, we use free space optics communication (FSO) with wavelength division multiplexing (WDM) technology to build a flexible yet high-performance logical network responsible for management traffic. The FSO-WDM can provide reconfigurable multi-terabit topology over line-of-sight (LoS) links. Due to space and processing capacity reasons, we can not offer direct connections from every data rack to the network management racks. Alternatively, the data racks are grouped together as each group is serviced for a duration of time matches its average arrival-rate. Since the data racks showed different arrival-rates, the hotspot racks are allocated with longer service time. The evaluation results show that F4Tele carried out high throughput close to the expensive solution (benchmark).
